Biotin cofactor

WebBiotin is a cofactor for carboxylase enzymes. There are five human enzymes for which biotin is a coenzyme: acetyl-CoA carboxylase I (soluble cytoplasm), acetyl-CoA carboxylase II (mitochondrial fatty acid oxidation), pyruvate carboxylase, methylcrotonyl-CoA carboxylase, and propionyl-CoA carboxylase. Acetyl-CoA carboxylase II … WebFatty acid synthase (FAS) carries out the chain elongation steps of fatty acid biosynthesis. FAS is a large multienzyme complex. In mammals, FAS contains two subunits, each containing multiple enzyme activities. In bacteria and plants, individual proteins, which associate into a large complex, catalyze the individual steps of the synthesis scheme.
